What is an eSIM

The term “eSIM” simply means embedded SIM card.  Basically, there are no physical SIM cards involved and no physical swapping over required by you. Niiice!


eSIM needs to be supported by the network or carrier and enabled by them, so for your new iPhone XS or XS Max — you’ll need to choose an eSIM-compatible network for the second SIM support.

Networks haven’t really adopted eSIMs as yet, but Apple’s work will make them adopt one step at a time.

The information on an eSIM is rewritable, meaning you can decide to change operator with a simple phone call.

They’re really easy to add to a data plan – connecting devices with eSIMs to a mobile account can be done in minutes, and they can be connected to multiple networks as well with multiple eSIMs.

An eSIM is basically a small chip inside your phone and works in a similar way to the NFC chip inside your phone.

Note that there is a physical SIM slot in the XS and XS Max – the eSIM inside these handsets is used for the second SIM support.

eSIM is great for regular travellers

Theoretically, eSIM should mean that you could go to another country and simply add a roaming eSIM to your handset while retaining access to your main “home” number.

That’s one of the disadvantages currently because, if you change SIMs abroad, for example, you can’t access your own number.

“eSIMs have the potential to eliminate roaming charges abroad”, says Truphone’s Steve Alder. “It also enables people to switch operators quickly to get connected if they’re in an area with no signal, frees up space for new features or additional battery life and could lower the risk of device theft.

“As consumers and operators begin to see the benefits, mass adoption of eSIMs will be inevitable.”

What does eSIM mean for devices?

One of the advantages it offers from a design point of view is that you make a smaller device because there’s no need to accommodate a SIM card or the tray that holds it.

There’s also no need for networks to manufacture or distribute lots of SIM cards.

So there you go…
